How Do You Know That?
The project will rely whenever possible on the first-hand accounts of the participants or the second-hand accounts of people who have communicated directly with the participants. It will document the sources of all such accounts. When a third-hand account with reference notes is found, the reference will be followed if possible to the original first-hand or second-hand account. Third-hand accounts without reference notes will be relied upon only as a last resort.
